To afZZ whom it may concern,.- V

Be it known that I, FRIEDRICH MEINZER, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga, State of Ohio, have invented certain new and useful Improvements in Heating Apparatus, of which the following is a specification, reference being had therein to the accompanying drawings. v

rlhis invention relates to a heating appara tus, and particularly to aconstruction adapted to heat air and water and also produce steam for such purposes as may be desired.

The invention has for an object to provide a construction'of water-heating and steamproducing means adapted for application to :he top of an ordinary stove, range, or other form of cooking apparatus, which can be easily swung out of its operative position above the lire-box or burner, and when thus swung the circulation of water therein is cut olf by means of the rotary or swinging valve forming the hinge-joint for the heating apparatus.

A further object of the invention is to produce a steam-pan in which heated water Inay be introduced and steam generated, said pan being mounted so as to oscillate upon aswinging valve and to be removed from the top of the stove when not in use.

Another object of the invention is to provide a meansfor heating air and conveying the same to any point desired, the motor for.

Other and further objects andadvantagesv of the invention will be hereinafter set forth and the novel features thereof defined by the appended claims.

In the drawings, Figure l is a perspective of the invention applied to a range-top; Fig. 2, a horizontal section on the line 2 2 of Fig. 1 with the steam-pan raised; Fig. 3, a central vertical section; Fig. 4., a sectionaldetail of the swinging valve; Fig. 5, a similar view of the check-valve within the steam-pan; Fig. 6, a longitudinal section through the steampan on the line 6 6 of Fig. l, and Fig. 7 is a detail perspective of the feed-valve for the steam-pan.

Like letters of reference refer to like parts in the several figures of the drawings.

carried by the plate.

This invention is adapted to be applied to any form of heating or cooking apparatus and is here shown in connection with the top A of a range, which is providedwitha smoke-pipe A at the rear and the usual warming-closet A2 adjacent to the said pipe and provided with the swinging door A2. When the present invention is used, the ordinary lids are removed, so as to permit the reception within the stove top of the plate B, which carries the water-heating coil B uponts under face, one of said plates beingshown open in Figs. l and 2. These plates are pivotally mounted at the front and rear, respectively, of the top by means of the swinging valves B2, whichare connected to pipe-sections B3, communicating with the opposite ends of the coil B, The rotary or swinging valves may be of any preferred construction, but are here shown as comprising-the sleevesection B4, Carried at theend of al pipe B5, and the plug B6, fitted therein and communicating with a pipe BT, said plug vbeing provided with an opening B8, adapted to communicate with the pipe B5 when the parts are in the position shown in Fig. 4, but at other times to cutoff the passage or circulation of any liquid through the valve.

For the purpose of establishingwater connections with these water-heaters' a circuit of pipes is provided, as will be hereinafter described, although I do not intend to'confine my invention specifically thereto, as other arrangements may be used to accomplish the same results. I have, however, shown a form particularly adapted to the construction herein presented, which comprises a pipe C, intended to be connected with a main or other source of water-'supply under pressure and 'provided with the coupling having upon one carried by the under surface of the steampan, which coil at its opposite ends extends upward into the steam-pan and is provided withy a feed-valve D3, as shown by detail in Fig. 7. This valve is provided with -outletopenings D4 adjacent to a valve-disk D5, which reciprocates within a casingD and rests upon the upper end of the pipe-,section D7,`so'as to admit the heated water by operating the pushrod I into the'steam-pan D, yet pre-vent the return of suoli water through any of the connecting-pipes. This valve D3 also-communicates with a hotwater pipe H', extending from the conducting-pipe H, which communicates with the outlet from the heating-coil carried by the inner water-heater, so that the heated water therefrom is discharged into the steam-v pau in connection with that from the heatingcoil D, carried by the pan. provided with a swinging valve H2 at its inner end, by means of which in connection with a similar valve C5 at the opposite end the pany may be swung into a substantially vertical position, as shown by full-lines in Fig.

Similar swinging valves C0 are-provided at the point of connection between the pipes H and C4 to permit the movement of the pan relative to ythe pipes. The lower surface of the pan D may bevprovided with recessed portions DS, extending inward for the purpose of providing increased radiating-surface for the generation-of steam from the hot water contained Within the pan, and a suitable watergage D0 is provided upon the pan, as shown in-Fig. 1. At one end of the pan a steamoutlet D10 is' provided, which is adapted to re- Inova bly connect with a coupling S', carried by the steam-pipe S, which is `provided withavalve .S2 adjacent to said coupling. This connectionl may be made in any manner-for instance, by means of the pipe D12-extending iuto'the coupling S and held in Contact therewith by means of a lever E, pivotally mounted at E upon a relatively tixed part and provided with a handle E2, which when depressed causes the leverto contact with the pipe D10 and hold the same in4 engagement with theA 1 coupling S'. 1 The steam-pipe S extends to the tends to the steam-pan, whereit may-be re movably connected, as shown at F3, while the end of this shaft F is provided with a ratchet- Wheel F1 and handle F5, secured upon the face of the wheel for rotating the same, While the wheel may be held in any desired position by means ofthe pawl-F, as shown-in Fig. l. Adjacent to this shaft` sockets F7 are provided upon the side walls of the Warming-closet'and adapted to receive rods F8, which are pivot- This pipe Il is' ally mounted therein and adapted to swing under the cover A3 when opened or to form supports for drying any articles which may be hung thereon.

The outer heating-coil B' is provided at its discharge end with a hot-water pipe H3, extending toward the rear of the stove and there connected by a coupling'H1 with the pipe-H from the inner coil B. The hot water is carried thence through the pipe H5 to the radiating-coil H0 at the rear ofthe stove and discharged'therefrom by the pipe H7, which is provided with a draw-off cock H8 and with a connection H0, which may extend to a stand boiler orreservoir and is provided wit-h a turncock H10.

At the rear of the smoke-pipe A' and radiating-coils H0 and S3 a fan G is located andy .provided with an entrance-funnel G to receive the heated air from the coils and pipe and convey the same by means of the pipe G2 to any desired point for heating an adjacent room or other purpose. This fan may be operated in any desired manner, but is here shown as provided upon its shaft G3 with a water-wheel G1, located within a closed casing G5 and provided with a cold-water connecting-pipe C1, having a turn-plug CS therein and extending through the casing, so 'as to rotate the water-Wheel -by impact therewith, While the discharge from the casing may be carried to any suitable point by means of the pipe C0, extending from the lower portion thereof. The steam-pan may be provided with any suitable form of feed-valve-for instance, as in Fig. 7, a crank-arm I may be connected to the valve disk and rod, while the latter is surrounded by a spring l2 to normally close the valve. Y

From the foregoing description the coustruction Yand general operation of the parts will be understood, and it is only desired to note that the inlets for the cold water extend at one side of the stove to each of the heating-coils therefor, while' at the opposite side the discharge-pipes for the hot water and steam extend. The cold wateris thus brought into contact with a coil directly over the lire and quicklyheated, so that it can be at once used, while'if the steam-pan be raised into its vertical position there would be no circulation therethrough, and the4 top of the stove is left perfectly free for cooking in the ordinary manner. When the steam-pan is lowered, the water is heated by the coils B' and D2 before entering the pan, so that steam vis quickly generated therein-and passes through the steam-pipe and radiating-coil to any suitable point of discharge or use, and this coil, in

connection with the hot-water coil at the opposite side of the stove, thoroughly heats the air, which is drawn by the fan andl forced to the room to be heated, while if the invention be used in a large kitchen the steam-discharge can be carriedto steam-pans, while the hotwater discharge may be carried to a suitable stand-boiler for washing purposes. It` will IOO IIO

therefore be seen that this invention provides means for secu ring hot air and hot water without interfering with the use of the stove-top for ordinary cooking purposes, while when the steam-pan is lowered it may be used for a similar purpose and would prevent the burning of articles which could not ordinarily be safely cooked upon the directlyheated stove-top.

While the several devices herein shown are operatively connected with each other and cooperate in their results, still it will be apparent that they may be independently used when desired and that changes may be made in the detailsof construction and configuration thereof without departing from the spirit of the invention as defined by the appended claims.

Having described my invention and set forth its merits, what I claim, and desire to secure by Letters Patent, is-
